Does the menstrual cycle affect how the body responds to stress?
Women in the luteal phase show a stronger cortisol response to laboratory stress than women in the follicular phase.
What they did
42 women not on hormonal contraceptives (24 in follicular phase, 18 in luteal phase) provided saliva samples during a normal day and during a stressful virtual reality task. Researchers measured cortisol in the saliva.
What they found
Women in the luteal phase had higher cortisol after the stress task (5.96 nmol/L) compared to women in the follicular phase (4.31 nmol/L). No other clear differences in daily cortisol patterns were found between the phases.
What it means for you
This suggests the body's stress response may be stronger in the luteal phase, possibly due to higher progesterone. This could affect how women experience stress throughout their cycle. The main limitation is the small sample size and the stress test was in a lab, so it may not reflect everyday stress.
